| Abstract | After they reach an aquatic environment, polychlorinated biphenyls (PCBs) and organochlorine(OC) tends to accumulate in organisms, because of their high hydrophobic property which then causesadverse effects. However, there are some factors that have an influence on the accumulation. The aim ofthis study was to investigate the effect of seasonal variation and lipid content on PCBs and OCaccumulation. Spot barb (Puntius bimaculatus) was selected as the representative of aquatic organismsbecause it is widely found across the country. Nine sampling stations located along the river receivingwastewater from surrounding farms, domestic, and industrial areas. Twenty fish (in each station) werecollected by using floating nets in both dry and wet seasons for measurement of PCBs and OC in thesamples. The results indicated that both PCBs and OC concentration in fish collected in the dry seasonwas higher than that in the wet season. These findings could be explained by the characteristics of waterchannels in the dry season which are quite stagnant, resulting in toxicants being adsorbed onto organicmatter surface and then becoming feed for the fish. For the effects of lipid content, the results showedthat PCBs/OC concentrations and lipid content were of significant positive correlation (p ? 0.05) in bothdry and wet seasons. This phenomenon might be the result of hydrophobic property of toxicants whichmake it accumulate in lipid tissue |
